![]() Trip_temps means the range of temperature, it’s a way to estimate the temperature and determine the fan condition. Which is the suggested tachometer reference? and how is it managed? I can’t find documentation in the Jetson Nano Developer Kit User Guide concerning the tachometer, nor in the Jeston Nano Supported Component List In addition, what do they mean RRU and RRD? Then I doubt which real RPM will be set after typing the above command to pass 255 to /sys/devices/pwm-fan/target_pwm I still would like to have answers for my previous questions.īut I’ve seen that checking the file /sys/bus/platform/devices/pwm-fan/pwm_rpm_table I get this table: (Index, RPM, PWM, RRU, RRD) I’m using the automatic fan control solution, that is working well, however I would like to know how to control the fan manually just in case I need it. /firmware/devicetree/base/pwm-fanĭrwxr-xr-x 2 root root 0 sep 30 10:06 power Lrwxrwxrwx 1 root root 0 sep 30 10:06 of_node ->. rw-r-r- 1 root root 4096 sep 30 10:06 kickstart_params rw-r-r- 1 root root 4096 sep 30 10:06 driver_override Lrwxrwxrwx 1 root root 0 sep 30 10:06 driver ->.
